Following 2 statements look identical to me, however the first one returns
only one object but the second one returns correctly an array of 4 objects.
What is happening here is simple, I get all the Grade objects (1st one
using Grade.find(:all) and second one using Grade.all), and then filter out
all the grade objects where they have worksheets assigned to them.
*
*
*@grades = Grade.find(:all){|grade| Worksheet.find(:all,:conditions=>
['grade_id =?',grade.id]).count > 0}*
*
*
*@grades = Grade.all {|grade| Worksheet.find(:all,:conditions=>
['grade_id =?',grade.id]).count > 0}*
Can somebody explain why the results would be different for these 2
statements.
